List Price NTN Bearing Ball Braring SL04-5030NR Deep Groove Ball Bearing With Ultra-High Precision

Product Overview

The NTN Bearing Ball Bearing SL04 - 5030NR is a remarkable deep - groove ball bearing that stands out in the market due to its ultra - high precision. Manufactured by NTN, a globally recognized brand in the bearing industry, this bearing is designed to meet the most demanding requirements of various industrial applications.

Design and Construction

• Inner and Outer Rings: The inner and outer rings of the SL04 - 5030NR are crafted with meticulous precision. They are made from high - quality bearing steel, which offers excellent hardness and resistance to wear. The surface finish of these rings is extremely smooth, reducing friction during operation and ensuring a longer service life.
• Ball Design: The balls within the bearing are precisely engineered to have a uniform size and shape. This uniformity is crucial for the smooth rotation of the bearing. The high - quality material of the balls also enhances their durability, allowing them to withstand high loads and speeds without deformation.
• Cage Structure: The bearing features a well - designed cage that holds the balls in place. The cage is made from a lightweight yet strong material, which not only reduces the overall weight of the bearing but also ensures proper ball spacing. This helps in maintaining the stability of the bearing during high - speed rotations and under heavy loads.

Ultra - High Precision Features

• Tolerance Control: The SL04 - 5030NR bearing has extremely tight tolerance control. The dimensional accuracy of the bearing components is within a very narrow range, which is essential for applications that require precise positioning and smooth operation. This high precision ensures that the bearing can perform consistently, even in the most demanding environments.
• Runout Performance: The runout of the bearing, which refers to the deviation from a perfect circular motion, is minimized. This low runout performance results in reduced vibration and noise during operation. It also improves the overall efficiency of the machinery in which the bearing is installed, as less energy is wasted in overcoming vibrations.

Performance Advantages

• High Load - Carrying Capacity: Despite its relatively compact size, the SL04 - 5030NR can handle high radial and axial loads. This makes it suitable for a wide range of applications, from automotive transmissions to industrial machinery. The bearing's ability to distribute loads evenly across its components helps in preventing premature failure.
• High - Speed Capability: The ultra - high precision design of this bearing allows it to operate at high speeds. The low friction generated by the smooth surfaces of the rings and balls enables the bearing to rotate at high RPMs without overheating. This high - speed capability makes it ideal for applications such as machine tools and electric motors.
• Long Service Life: Thanks to its high - quality materials, precise manufacturing, and excellent performance characteristics, the SL04 - 5030NR has a long service life. It can withstand continuous operation for extended periods without significant wear or degradation, reducing the need for frequent replacements and maintenance.

Application Areas

• Automotive Industry: In automotive applications, the SL04 - 5030NR can be used in wheel hubs, transmissions, and engine components. Its high precision and load - carrying capacity ensure smooth and reliable operation of these critical parts, contributing to the overall performance and safety of the vehicle.
• Industrial Machinery: For industrial machinery such as pumps, compressors, and conveyors, this bearing provides the necessary precision and durability. It helps in reducing downtime and improving the efficiency of the machinery, leading to increased productivity.
• Machine Tools: In machine tools, the ultra - high precision of the SL04 - 5030NR is essential for achieving accurate machining results. It allows for high - speed and high - accuracy operations, ensuring the quality of the manufactured products.

Quality Assurance

NTN adheres to strict quality control standards during the manufacturing process of the SL04 - 5030NR bearing. Each bearing undergoes a series of rigorous tests, including dimensional inspection, hardness testing, and performance testing. This ensures that every bearing that leaves the factory meets the highest quality requirements and can provide reliable performance in real - world applications.

Compatibility and Installation

The SL04 - 5030NR bearing is designed to be compatible with a wide range of shafts and housings. It follows standard industry dimensions, making it easy to install in existing equipment or new machinery designs. However, proper installation procedures should be followed to ensure optimal performance. This includes cleaning the mating surfaces, using the correct tools for installation, and applying the appropriate lubrication.

Lubrication Requirements

Proper lubrication is essential for the smooth operation and long service life of the SL04 - 5030NR bearing. The bearing can be lubricated with various types of lubricants, such as grease or oil, depending on the application requirements. Grease lubrication is commonly used for general applications, as it provides good sealing and protection against contaminants. Oil lubrication is preferred for high - speed and high - temperature applications, as it offers better heat dissipation.

Environmental Resistance

The SL04 - 5030NR bearing is designed to resist the effects of various environmental factors. The bearing steel used in its construction has good corrosion resistance, which allows it to operate in humid or corrosive environments. Additionally, the surface treatment of the bearing components further enhances its resistance to rust and oxidation, ensuring reliable performance even in harsh conditions.

In conclusion, the NTN Bearing Ball Bearing SL04 - 5030NR is a top - of - the - line deep - groove ball bearing that offers ultra - high precision, excellent performance, and long - term reliability. Its wide range of applications, combined with its high - quality construction and strict quality control, make it a preferred choice for industries around the world. Whether you are looking for a bearing for automotive, industrial, or machine tool applications, the SL04 - 5030NR is sure to meet your needs.
